ROTARY KILN.

Specification of Letters Patent.

Patented March 19, 1907.

Application filed October 24, 1905. Serial No. 284,196.

T0 all whom, t may concern.

Be it known that I, WILLIAM R. WARREN, a citizen of the United States,residing at Manhattan borough, in the county of New York and State ofNew York, have invented new and useful Improvements in Rotary Kilns, ofwhich the following is a specic ation.

This invention relates to means by which the operation of the kiln canbe expedited or regulated and by which the operation of the kiln can beaccurately'observed.

This invention is set forth in the following specification and claim andillustrated in the annexed drawing, in which*M Figure l is a sectionalview of a kiln embodying this invention. Fig. 2 is a section along :c x,Fig. 1.

In the drawing is shown a rotary kiln comprising a shell or body part a.A partition is shown at b extending part of or all thelength of thekiln.

An intake c is adapted to introduce fuel or the like into the interiorof the kiln at an in termediate point or at a point or points of theouter shell between the ends of the same. One or more such intakes, asc, can be applied.

An intake or main fuel-inlet d is passed through an end of the kiln orouter shell a. About said main inlet is placed a stationarychamber-section e. tion f communicates with the first section, theointstherebetween being suitably tightene If any gas or the like is led bysupply g to the chamber ef, the same, passing through intake c, entersan inner or intermediate portion of the kiln. This intake c rotates withprlis secured by suitable fastenings h to the n n.

The word fuel above is intended to cover gas, air, or other material ormixture of materials.

The intake c can be used as required, for example, to convertnon-combustible matter in the kiln into combustible or to withdrawcontents of the kiln for analysis or other purposes. The air needed, forexample, for primary combustion or for the combustion of material from.the intake d can be supplied by intake c, or the pipe c can also be usedto introduce fuel for the main combustion or to withdraw contents fromthe kiln at a certain A rotary chamber-secl stage of the operation formaking a test or for other purposes.

The pipe or intake c can enter the kiln at the partition or at any otherintermediate point. The pipe c can enter at or through one or morepartitions, if desired.

This invention can be applied to kilns as now constructed withoutpartition or without being subdivided into compartments.

The shield i is shown removably connected to the shell or kiln bysuitable means7 such as straps le, which by turnbuckles or nuts m,engaging connecting-points, such as lugs or eyes n, can be tightened upto hold the shield to its place. The shield shown rotates with the kiln.

The clinker or other matter to be discharged at the outlet end can passout through suitable exits or holes in the shell, and shutters or thelike p can be slid or moved to close the holes or outlets more or less,as desired, for example, to regulate or vary the amount of air enteringthe kiln at this portion.

The regulatable closures p, in connection with the intake c, can beoperated to produce the best results in the combustion of the fuel.

. The kiln can be rotated by suitable mechanism, and one of the tires isshown at g of such size as to surround or engage the intake c.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. A rotary kiln having an inner .partition and an intake extendedthrough the shell and partition into the interior of the kiln.

2. A rotary kiln having an intake-opening into the kiln at a pointremoved from the wall of the body thereof and extended through and madeto rotate with the shell of such kiln.

8. A rotary kiln having an intake, a rotary chamber-section made tocommunicate with said intake, and another chamber-section made tocommunicate with or supply material to the rotary chamber-section.

4. A rotary kiln having an intake at one end, a rotary chamber aboutsaid intake, and another intake or supply made to communicate with thechamber and to enter an intermediate portion of the kiln.

5. A rotary kiln having a tube or intake IOO positioned exteliorly'thereof' and opening` therein, a tire arranged aroundr the periphery ofthe kiln and extending,` about the in take, said tire carrying theintake when the kiln rotates7 and a rotatable chamber-sectioncommunicating with a source of supply and carried upon the outer end olEthe intake.
